Colorectal cancer(CRC) is one of the most common malignant tumors worldwide, primarily originating from recurrent inflammatory bowel disease(IBD). Therefore, blocking the inflammation-cancer transformation in the colon has become a focus in the early prevention and treatment of CRC. The inflammation-cancer transformation in the colon involves multiple types of cells and complex pathological processes, including inflammatory responses and tumorigenesis. In this complex pathological process, immune cells(including non-specific and specific immune cells) and non-immune cells(such as tumor cells and fibroblasts) interact with each other, collectively promoting the progression of the disease. In traditional Chinese medicine(TCM), inflammation-cancer transformation in the colon belongs to the categories of dysentery and diarrhea, with the main pathogenesis being cold and heat in complexity. This paper first elaborates on the complex molecular mechanisms involved in the inflammation-cancer transformation process in the colon from the perspectives of inflammation, cancer, and their mutual influences. Subsequently, by comparing the pathogenic characteristics and clinical manifestations between inflammation-cancer transformation and the TCM pathogenesis of cold and heat in complexity, this paper explores the intrinsic connections between the two. Furthermore, based on the correlation between inflammation-cancer transformation in the colon and the TCM pathogenesis, this paper delves into the importance of the interaction between inflammation and cancer. Finally, it summarizes and discusses the clinical and basic research progress in the TCM intervention in the inflammation-cancer transformation process, providing a theoretical basis and treatment strategy for the treatment of CRC with integrated traditional Chinese and Western medicine.

BACKGROUND:The immune cell composition and functional states within the tumor microenvironment of epithelial ovarian cancer directly influence patient prognosis and therapeutic response.Recent studies indicate that CD4+T cells not only support anti-tumor immunity but can also exert direct anti-tumor effects under specific conditions.High infiltration of CD8+T cells is considered a positive prognostic marker.FOXP3+regulatory T cells play a crucial role in maintaining immune tolerance and modulating immune responses.OBJECTIVE:The data from 416 epithelial ovarian cancer patients along with clinical pathology samples from 21 patients were comprehensively analyzed utilizing bioinformatics algorithms to investigate the relationship between the expression of CD4+T cells,CD8+T cells,and FOXP3+T cells in the tumor microenvironment and survival outcomes in ovarian cancer patients.METHODS:(1)The study categorized 416 cases of epithelial ovarian cancer from the Ovarian Cancer subset of The Cancer Genome Atlas using the Non-negative Matrix Factorization algorithm.The CIBERSORT algorithm(Cell-type Identification By Estimating Relative Subsets Of RNA Transcripts)was employed to examine differences in immune cell infiltration between patients with high and low survival rates.(2)Multiplex immunohistochemistry was used to assess the expression of CD4,CD8,and FOXP3 in pathological tissue samples from 21 patients from Chinese People's Liberation Army General Hospital,and their association with patient prognosis was analyzed.RESULTS AND CONCLUSION:The high survival rate group exhibited significantly greater infiltration of immune cells,including CD4+T cells,CD8+T cells,and FOXP3+regulatory T cells,compared with the low survival rate group(P＜0.01).Results from the multiplex immunohistochemistry experiments revealed that high expression of FOXP3 was significantly correlated with better prognosis in ovarian cancer patients(P＜0.05).It is indicated that the expression of FOXP3 in the tumor microenvironment is associated with survival outcomes in epithelial ovarian cancer patients,suggesting that the infiltration of FOXP3+regulatory T cells in the tumor microenvironment is a key factor influencing patient prognosis.

Objective To study the three-dimensional changes of soft and hard tissue in male patients with unilateral non-syndromic cleft lip and palate in the mixed dentition period before and after maxillary protraction.Methods Twenty male patients with unilateral non-syndromic cleft lip and palate in the mixed dentition period treated by maxillary anterior traction in the Department of Orthodontics of Affiliated Stomatological Hospital of Nanjing Medical University were selected(average age(10.6±1.23)years old).Cone beam CT was taken before and after treatment.Dolphin 3D 11.95 software was used for three-dimensional measurement and analysis.SPSS 25.0 software package was used for statistical analysis.The self-controlled paired t test was used to compare the changes in soft and hard tis-sues of male patients with unilateral cleft lip and palate before and after treatment.The changes in the anterior displacement of the ANS point,the anterior displacement of point A,and the posterior displacement of point B were tested using the one-sample t test.Results The sagittal skeletal changes were significantly increased in ∠ SNA(P＜0.01),∠ANB(P＜0.01),Y axis(P＜0.05),the forward displacement of ANS point(P＜0.01)and A point(P＜0.01)and the backward displacement of B point(P＜0.01),but ∠SNB(P＜0.05)was decreased significantly.The vertical skeletal changes showed that ∠MP-FH(P＜0.01),∠MP-SN(P＜0.05)and the dis-tance of ANS-Me(P＜0.05)were increased significantly,but ∠SN-PP(P＜0.01)was decreased significantly.The dental changes inclu-ding ∠U1-NA(P＜0.01),the distance of U1-NA(P＜0.01),∠U1-SN(P＜0.01),overjet and the Wits were increased significantly,but ∠ L1-NB(P＜0.01),the distance of L1-NB(P＜0.01)and ∠L1-MP(P＜0.01)were decreased significantly.The changes of soft tis-sue including ∠ S-Ns-Sn(P＜0.01),∠ Sn-Ns-Bs(P＜0.01),the distance of UL-EP(P＜0.01)and LL-UL(P＜0.01)were increased sig-nificantly.Conclusion After the treatment of maxillary protraction,the forward growth of maxilla will be possibly promoted on patients with cleft lip and palate in the peak of growth timing,as well as the intermaxillary relationship and soft tissue profile,but the side effects should be paid attention to.

Objective: To investigate the factors affecting depression and anxiety symptoms among the elderly, so as to provide the basis for promoting mental health among the elderly. Methods: The elderly aged 60 years and above in Ningbo City, Zhejiang Province were recruited using the multistage stratified random sampling method from June to August 2022, and demographic information, lifestyle and self-rated health status were collected by questionnaires. The symptoms of depression and anxiety were assessed by the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7), respectively. The presence of depressive and anxiety symptoms was determined when both the PHQ-9 score and the GAD-7 score were 10 points and higher. Factors affecting depressive and anxiety symptoms were identified using a multivariable logistic regression model. Results: A total of 7 771 individuals were surveyed, including 3 490 males (44.91%) and 4 281 females (55.09%), and had a mean age of (72.11±6.79) years. The prevalence of depression and anxiety symptoms was 2.05%. Multivariable logistic regression analysis identified residence (urban area, OR=0.316, 95%CI: 0.201-0.498), sedentary duration (<3 h/d, OR=0.349, 95%CI: 0.232-0.525; 3-5 h/d, OR=0.458, 95%CI: 0.313-0.671), physical activity (≥3 times/week, OR=0.551, 95%CI: 0.373-0.815), sleep quality (poor, OR=2.491, 95%CI: 1.738-3.571), social isolation (OR=1.688, 95%CI: 1.148-2.481) and self-rated health (poor, OR=5.857, 95%CI: 3.547-9.671; normal, OR=1.903, 95%CI: 1.234-2.937) as the influencing factors for depression and anxiety symptoms among the elderly. Conclusion The prevalence of depression and anxiety symptoms among the elderly is associated with residence, sedentary duration, sleep quality, physical activity, social interactions and self-rated health status.

Objective:To analyse the characteristics of micronuclus and chromosomal aberrations and the lens opacity in different working years, ages and work type of radiation workers with lens opacity.Methods:In January 2022, we selected 400 radiation workers with lens opacity who had undergone occupational health examination in Hangzhou Hospital for the Prevention and Treatment of Occupational Disease from March 2014 to December 2021 as research objects. To analyze the differences of micronucleus, chromosome aberration and the lens opacification rates of different length of service, type of work, age radiologic workers.Results:The results showed that radiation the micronucleus abnormality (0.59‰) and chromosome aberration (2.67%) in peripheral blood in workers who served more than 20 years were significantly higher than that of micronucleus abnormality (0.18‰) and chromosome aberration (0.31%) in workers served less than 20 years, the differences were statistically significant ( P<0.05). The micronucleus abnormality (0.32‰) and chromosome aberration (0.57%) in the interventionist were higher than oral radiation workers (0.12‰ and 0.19%) and diagnostic radiologist (0.05‰ and 0.12%), the differences were statistically signcficant (χ 2=23.98, 6.72, P<0.05) . Conclusion:The rates of micronucleus and chromosome aberration of the interventionaist are higher than oral radiation workers and the traditional radiologist. Workers engaged in radiation should improve personal protection and undertake regular occupational health examinations.

Objective To investigate the clinical effect of air moxibustion combined with pushpin-like needle acupuncture,which is formulated based on the"suppressing wood-supporting earth"theory in the doctrine of the five elements of Traditional Chinese Medicine(TCM),in the treatment of pain,nausea and vomiting after transcatheter arterial chemoembolization(TACE).Methods A total of 160 patients with hepatocellular carcinoma,who were admitted to the First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine of China to receive initial TACE between July 2020 and June 2023,were enrolled in this study.The patients were randomly divided into 4 groups with 40 patients in each group.The patients of the control group received TACE with conventional nursing care,the patients of the pushpin-like needle group received pushpin-like needle acupuncture on the basis of the control group,the patients of the air moxibustion group received air moxibustion treatment on the basis of the control group,and the patients of the combination group received air moxibustion combined with pushpin-like needle acupuncture on the basis of the control group.The post-TACE pain degree(VAS scoring)and nausea/vomiting extent(INVR scoring)were compared between each other among the four groups.Results The differences in the VAS score and INVR score(including main effect and interaction effect)between each other among the four groups were statistically significant(all P＜0.05).Statistically significant differences in the VAS score and INVR score existed between the control group and the other three groups(all P＜0.05).The differences in the VAS score and INVR score between combination group and pushpin-like needle group,as well as between combination group and air moxibustion group were statistically significant(both P＜0.05).Conclusion Air moxibustion combined with pushpin-like needle acupuncture can effectively and remarkably relieve post-TACE pain,nausea and vomiting,which is superior to simple use of air moxibustion or pushpin-like needle acupuncture.Therefor,the combination use of air moxibustion and pushpin-like needle acupuncture should be popularized in clinical practice.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.
